Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Referring to fig. 1-3, the present invention provides a technical solution: the utility model provides a safe automobile accelerator pedal, includes fixing base 1, fixedly connected with mount 12 on the fixing base 1, and fixed mounting has rotary joint 6 on the mount 12, and mount 12 rotates through rotary joint 6 and installs pedal arm 3, and fixedly connected with shell 8 on the fixing base 1, fixedly connected with linking arm 9 on the shell 8, and the lateral part of pedal arm 3 is provided with stopper 5, is provided with safe trigger unit 2 on the fixing base 1.

The safety trigger unit 2 comprises a base 11, the base 11 is fixedly connected with the side part of the fixed seat 1, an emergency switch 16 is installed on the base 11, the upper part of the base 11 is fixedly connected with a crushing part 13 which covers the emergency switch 16, a fracture grid 15 is arranged on the crushing part 13, the emergency switch protected by a top easy crushing structure is additionally installed, a grid-shaped fracture is arranged on the easy crushing structure, a certain gap is reserved between the easy crushing surface and the top of the switch, when the pedal 4 is treaded on vigorously, a limiting block crushes the easy crushing surface to trigger the emergency switch on the lower part, the power control system receives the output of the braking force limited by the switching signal, if necessary, the braking is assisted to avoid the accident, the accident caused by mistaken treading can be effectively prevented by making a small change on the basis of the original pedal structure, and the safety trigger has obvious advantages in safety compared with the existing common electronic accelerator pedal, because of the mechanism that the emergency switch is triggered by the crushing of the accelerator pedal, the accelerator pedal has a good effect of preventing traffic accidents caused by mistaken stepping of a driver.

Fixedly connected with footboard 4 on the footboard arm 3, footboard 4 all sets up to the arc structure with footboard arm 3, and curved footboard 4 makes things convenient for vehicle driver's foot to trample with footboard arm 3 structure.
